Given numbers are 479,721,957,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,721,957,642 is 70728832482.
Find LCM of 479,721,957,642 with Prime Factorization
3 | 479, 721, 957, 642 |
479, 721, 319, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 479 x 721 x 319 x 214 = 70728832482
Therefore, the lowest common multiple of 479,721,957,642 is 70728832482.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
479 x 721 x 957 x 642 = 212186497446
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
479 : 1, 479
721 : 1, 7, 103, 721
957 : 1, 3, 11, 29, 33, 87, 319, 957
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,721,957,642, is 1.
Now, the common factors can be found like this.
479:479
721:7x 103
957:3x 11x 29
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 212186497446/(1x3)
LCM = 212186497446/3
LCM = 70728832482
Thus, we can understand that the LCM of 479,721,957,642 is 70728832482.
